As board designs have migrated away from large amounts of logic chips, so has the need for many of the same gate in one package. Minimum count enable time is the interval immediately preceeding the rising ci of the clock pulse during which interval the count enable input must be low to ensure counting. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of Tl products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by Tl.

Further, Buyers must fully indemnify Tl and its representatives against any damages arising out of the use of Tl products in such safety-critical applications. Tl assumes no liability for applications assistance or customer product design.

Digital electronics Electronic design Electronics lists Integrated circuits. The input pulses are supplied by generators having the following characteristics: Data in is shown by the solid line for both devices. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

However, different manufacturers will use different prefixes or no prefix at all. All chips in this section have three gates, noted by the “3G” in the datasheeg numbers. Surface mount parts with a single gate often in a 5-pin or 6-pin package are prefixed with G instead of Welcome to our site!

Buyers acknowledge and agree that any such use of Tl products which Tl has not designated as military-grade is solely at the Buyer’s risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

Data inputs A and D are shown by the solid line. For more details, refer primarily to the Texas Instruments documentation mentioned in the References section.

By using this site, you agree to the Terms of Use and Privacy Policy. All datazheet in the following sections are available 4 to 12 pin surface mount packages. All chips in this section have one gate, noted by the “1G” in the part numbers. Older discontinued parts may be available from a limited number of sellers as new old stock NOSthough some are much harder to find.


Due to the popularity of these parts, other manufacturers have released pin-to-pin compatible devices which kept the sequence number as an aid to identification of compatible parts. Tl is not responsible or liable for such altered documentation. IC manufacturers continue to make a core subset of this group, but many of these part numbers are considered obsolete and no longer manufactured. The counters can be easily cascaded by feeding the ripple clock output to the enable input of the jc counter if parallel clocking is used, or to the clock input if parallel enabling is used.

All chips in jc section have two gates, noted by the “2G” in the part numbers. For a better experience, please enable JavaScript in your browser before proceeding. Full or half bridge capabilities.
